Procedure

A 50 mL flask was charged with 1-(3-(2-bromo-4-fluorophenoxy)-5-(3-methoxyphenylthio)pyridin-2-yl)thiourea (1.5 g, 3.12 mmol), triethylamine (0.740 mL, 5.31 mmol), tert-butyl 4-(2-bromoacetyl)piperidine-1-carboxylate (1.15 g, 3.75 mmol), and EtOH (25 mL). The reaction was heated to 70° C. for 2 hours. The reaction was partitioned between EtOAc and water. The organic layer was dried with sodium sulfate, filtered and concentrated. The residue was purified on silica (10% EtOAc in hexanes) to afford tert-butyl 4-(2-(3-(2-bromo-4-fluorophenoxy)-5-(3-methoxyphenylthio)pyridin-2-ylamino)thiazol-4-yl)piperidine-1-carboxylate (1.76 g, 82.0% yield).
